Instructions:
  • Answer 50 questions in 30 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. A freely moveable joint; also known as a diarthrosis.






2. The vertebrae of the pelvic region; fuse to form a solid structure which forms a joint with the ilium called the sacroiliac joint.






3. The epiphyseal plate of a long bone; located at the junction of the proximal and distal epiphyses with the diaphysis. Areas where long bones increase in length by the process of endochondral bone formation. When an animal reaches its full size - thes






4. An alternate name for joint cavity.






5. The main - weight - bearing bone of the lower leg; forms the stifle joint with the femur proximal to it and the hock with the tarsus distal to it.






6. The large process on the proximal end of the ulna that forms the point of the elbow; the site where the triceps brachii tendon attaches.






7. The membrane that encloses the ends of the bones in a synovial joint; consists of an outer fibrous membrane and an inner synovial membrane that produces viscous synovial fluid that lubricates the joint surfaces.






8. The cartilaginous disk located between the bodies of adjacent vertebrae; acts as a shock absorber for the vertebrae.






9. Another name for cancellous bone.






10. The hormone secreted by the parathyroid gland that prevents the level of calcium in the blood from getting too low.






11. Small cavities within the matrix of some connective tissues - such as cartilage and bone - within which cells are contained.






12. The long bone of the brachium or upper arm.






13. A skull bone that is one of the external bones of the cranium; the caudal - most bone of the skull that forms the atlanto - occipital joint with the first cervical vertebra through the occipital condyles. The large foramen magnum in the occipital bon






14. The hematopoietic type of bone marrow.






15. The vestigial metacarpal and metatarsal bones of a horse's leg. There are two spint bones in each leg: one on either side of the cannon bone (MC/MT III). The medial bone is MC/MT II and the lateral bone is MC/MT IV.






16. Secondary areas of growth in bones developing by the endochondral method; areas of bone development located outside the main portions of the carilaginous bone templates in a developing fetus.






17. The junction between two bones; can be completely immovable (fibrous) - slightly movable (cartilaginous) or freely movable (synovial).






18. A rib whose costal cartilage joins the costal cartilage of the rib ahead of it instead of directly joining the sternum.






19. Skull bones that are external bones of the cranium; form the lateral walls of the cranium - contain the middle and inner ear structures - and are the skull bones that form the temporomandibular joints with the mandible.






20. The smallest and most medial of the three pairs of bones that make up the pelvis; forms the cranial portion of the floor of the pelvis.






21. The soft material that fills the spaces inside the bones; two types of bone marrow are red bone marrow - which forms blood cells - and yellow bone marrow - which consists primarily of adipose tissue.






22. Spongy bone; a form of bone composed of a seemingly random arrangement of spicules of bone separated by spaces filled with bone marrow. Appears spongelike to the naked eye. Found in the ends of long bones and the interiors of short bones - flat bones






23. The lay term for the most proximal joint of the equine digit - which is the joint between the large metacarpal or metatarsal and the proximal phalanx. The proximal sesamoid bones are located on the caudal surface of this joint.






24. A space within a skull bone that is an outpouching of a nasal cavity; depending on the species - these are found within the frontal bones - maxillary bones - sphenoid bones - and ethmoid bones.






25. The single - dorsally projecting process of a vertebra.






26. The long bone of the thigh region; it forms the hip joint with the pelvis at its proximal end and the stifle joint with the tibia at its distal end.






27. The bones of the limbs (appendages)






28. One of countless tiny channels through the matrix of bone that bring blood in from the periosteum to the haversian canals in the centers of the haversian systems. The haversian systems run lengthwise in long bones while these canals come in at right


29. A joint that allows only a rotary motion; the only true joint of this type is the atlantoaxial joint ('no joint').






30. The most caudal of the three pairs of bones that make up the pelvis.






31. A joint motion whereby the distal end of an extremity moves in a circle.






32. The fibrous membrane that covers the outsides of bones except for their articular surfaces.






33. The 'horn core' of horned animals; a process of the frontal bone. The hollow cavity within this process is continuous with the frontal sinus (the paranasal sinus of the frontal bone).






34. A toe made up of two or three boens called phalanges.






35. The main growth area of a bone developing by endochondral method; areas of bone development that are located in the main portions of the cartilage rod bone templates in the developing fetus.






36. The bone in the neck region that supports the base of the tongue - the pharynx - and the larynx - and aids the process of swallowing. It is usually referred to as a single bone - but it is composed of several portions of bone and cartilage.






37. Also called a spheroidal joint - it consists of a spherical joint surface (the ball) that fits into a closely matching - concave joint surface (the socket). Examples: shoulder and hip joints. Capable of all synovial joint movements.






38. The joint composed of the tarsal bones; referred to as the hock in most animals and the ankle in humans.






39. A large - rounded articular (joint) surface; examples are found on the distal ends of the humerus and femur.






40. Skull bones that are external bones of the face; form a portion of the orbit of the ey and the rostral portion of the zygomatic arch.






41. The bony canal in the temporal bone that leads into the middle and inner ear cavities of the bone; in the living animal - it contains the external ear canal.






42. Skull bones that are part of the internal bones of the face; make up the caudal portion of the hard palate.






43. The area of a bone that joins the head with the main portion of the bone.






44. A joint movement that consists of a twisting motion of a part on its own axis.






45. The cartilaginous ventral portion of a rib.






46. Skull bones that are part of the external bones of the face; these two bones are the most rostral skull bones and contain the upper incisors in all domestic animals except ruminants.






47. A bone whose shape does not fit into the long bone - short bone - or flat bone categories. Bones either have characteristics of more than one of the other three shape categories or have a truly irregular shape. Includes vertebrae and sesamoids.






48. An arthrodial joint in which two flat articular surfaces rock on each other; the carpus is an example.






49. A hinge joint in which one articular surface swivels around another; the only movements possible are flexion and extension.






50. Skull bones that are part of the external bones of the face; form the bridge of the nose or the dorsal part of the nasal cavity.
